Abstract
The utility model relates to an improved structure on a bearing ball retainer. Both sides of the retainer body are respectively provided with a row of mutually staggered ball packet holes openings of which are outward; the outer sides of the packet holes are provided with laminar ball protection sheets which are gradually thin from inner part to the outer part according to need; the inner edges are ball surface extension part of the ball packet holes. Thus, the utility model has the advantages of simple structure, compact structure, reasonable arrangement and smaller volume; two rows of balls are arranged in a small space so that the utility model has the advantages of high strength, big load, high reliability and durability, etc.
Description
The utility model relates to a kind of mechanical bearing, especially to the structure improvement of a kind of ball retainer in the bearing.
The structure with holes that existing ball retainer adopts the punching out of steel thin slice to become more perhaps adopts materials such as plastic cement, nylon to make retainer with holes, and a row ball is kept the spacing that suits each other, with guarantee bearing normally, operation reposefully.Though this traditional structure has its intrinsic characteristics, but still exist making, assembling inconvenience, can only keep a row ball usually, bulk is bigger, and structural strength is owed high deficiency.
Goal of the invention of the present utility model provides a kind of two row balls rationally can arrangements and is set together, and it is little to make it volume, intensity height, the Ball retainer that reliability and serviceability are high.
Respectively be provided with row dislocation each other on the both sides of described support body, and opening ball pocket hole outwardly.Make two row balls interlaced with each other, and almost equidistantly be distributed in the both sides of Ball retainer, and rely on structure such as race ring that it firmly is fixed in one.
Wherein, structure is set designs according to shaft strength direction or size of ball pocket hole in the support body.For example, the ball pocket aperture on surface, outer ring can be half hole that equals or be slightly larger than ball diameter in the described support body, and the pearl pocket aperture of inner peripheral surface is half hole of small aperture.Ball is inserted from the support body top, rely on and fix from the structure of outer ring and both sides; Also can surface, the outer ring in the described support body is symmetrical with the ball pocket aperture of inner peripheral surface, and its outer rim is the diameter place in ball pocket hole.Ball is inserted from both sides, and rely on the structures such as steel ring that are positioned at its both sides to fix.
The side that each the ball pocket hole perforate of the both sides of described support body is outer is provided with a shape and is the outwards gradually thin laminar sheet of keeping, and its inner rim is the extension of ball pocket hole sphere, and its base portion thickness is half of thickness between the two ball pocket holes.It is described that to keep the direction that sheet is provided with all consistent.Make it to make, easy to assembly, do not influence ball running within it, and be beneficial to the location etc. of ball.
The right integral molded plastics such as nylon, plastics that adopt of described support body are made, about two row ball pocket holes alternately arrange, minimum clearance therebetween is the 0.4-0.6 millimeter.
Therefore, the utlity model has simple in structure, compact, connection and reasonable arrangement, volume is less, can arrange two row balls in less space, make it the intensity height, load is big, characteristics such as reliability and serviceability height, and solved problems such as the hot working thin-walled problem of single retainer and little spacing installation, can be widely used in mechanical transmission, especially occasion such as automobile bearing transmission.
Fig. 1 is a kind of main TV structure schematic representation of the present utility model.
Fig. 2 is the local unfolded drawing of the A-A of Fig. 1.
Fig. 3 is the partial structurtes enlarged view of Fig. 2.
Below by embodiment, and in conjunction with the accompanying drawings, structure of the present utility model is further described.
Embodiment: it is outside that the both sides interlaced arrangement that retainer ties up to support body 1 is provided with opening, and be the ball pocket hole 2 of equal distribution, and the size in its hole is slightly larger than ball diameter, makes it ball and goes slick therein.Wherein, the aperture in the ball pocket hole in the inner peripheral surface of support body and its surface, outer ring is symmetrical, its edge be provided with by ball pocket hole extend form and from the inside to the outside wall thickness gradually thin keep sheet 3, its base portion thickness be two ball pocket Kongzuis closely spaced half, be 3 millimeter.Above-mentioned all structures all adopt the nylon material integral molded plastic to make.
When reality is used, support body 1 described in the utility model can be arranged on the bearing inner ring, ball is inserted from its both sides, and is kept by the sheet 3 of keeping of its outer rim, in case ball falls down, and then parts such as outer race is assembled into one by known process engineering.
